Quality Control Requirements - 12 Kits at a Time
To test 12 kits at a time, it is useful to set up rapid testing procedures for parts.
From the 3D Printer Packing List:
Perfect Prints
To guarantee perfect prints, the following conditions must be met:
- Extruder steps per mm are correct. See Triffid Hunter's Calibration Guide
- Axes must be able to move freely. See 3D Printer Manual - final assembly for procedure to mount axes
- Axis range of motion must be over the entire bed. Do D3D Burn-In for 20 minutes to verify all motion.
Corresponing Quality Control Steps for Perfect Prints
Burn-In
See document above.
Bed Adhesion
- Optimize Z offset from extruder. Measure variation over multiple prints and graph.
- Optimize heated bed temperature. Measure force required to pull a columnar object off the bed using a digital scale
Smooth and Tight Motion
- Measure axis tightness using a force meter. Use a Digital Scale to record the force required to move an axis.
Extrusion
- E steps/mm must be done only once, and must be captured in Marlin or in Start G-Code
- Optimize temperature for a given filament. See Triffid Hunter's Calibration Guide
